Patent GB-672727-A (GB)
Title: Manufacture of new naphthyl-propionic acids and functional derivatives thereof
IPC: C07C57/40
Filed: 1949-08-02
Abstract: b  - (2 - Naphthyl) - a  : a  : b  - trialkylpropionic acids unsubstituted in the 6-position of the naphthalene ring, and esters and nitriles thereof, are manufactured from 2-naphthyl alkyl ketones (unsubstituted in the 6-position) by reaction in the presence of a metal (and preferably also an inert solvent) with a halogen-acetic acid ester, of which the acetic acid residue is not further substituted or is mono- or di-alkylated, replacement of the hydroxy group in the resulting tertiary carbinol by hydrogen (directly, e.g. by heating with hydrogen iodide and red phosphorus, or indirectly, e.g. by dehydration followed by hydrogenation), or by replacement of the carbonyl group by a halogen-methylene group by reduction to the carbinol and replacement of the hydroxy group by halogen, reaction of the resulting 2-naphthylalkylmethyl halide in the presence of a metal with a halogen-acetic acid ester which may be mono- or di-alkylated in the acetic acid residue and, in either case, when necessary, introduction into the a -position of the propionic residue of any alkyl group which may be lacking (e.g. by the action of an alkyl halide, advantageously in the presence of sodium triphenylmethyl and an inert organic solvent); or from esters or nitriles of (2-naphthoyl)-dialkylacetic acids (unsubstituted in the 6-position) by reaction with a metal compound of an aliphatic hydrocarbon and replacement of the hydroxy group in the resulting carbinol by hydrogen (if desired after hydrogenating aliphatic carbon-to-carbon multiple bonds), or by reaction in the presence of a metal with an ester of a halogen-acetic or b -halogen-propionic acid, replacement of the hydroxy group in the resulting carbinol by hydrogen, and replacement of the newly introduced esterified carboxyl group by hydrogen or alkyl (e.g. by selective hydrolysis followed by the Hoffmann, Curtius or Nägeli degradation and replacement of the resulting amino group by hydrogen by treatment with nitrous acid followed by reduction of the hydroxy group, or by reduction of the corresponding acid halide group through an aldehyde and/or a hydroxymethyl group to a methyl group).  In all cases the ester or nitrile obtained is, if desired, hydrolysed to the free acid, which may be converted into salts.  The products are useful as medicaments or intermediates therefor.  Examples describe the preparation of b -(2-naphthyl)-b -ethyl-a : a -dimethylpropionic acid and its methyl ester from 2-naphthyl ethyl ketone and from (2-naphthoyl)-dimethylacetic acid ethyl ester, each by two methods. Lists of additional starting materials and suitable reagents and solvents are given.  (2 - Naphthoyl) - dimethylacetic acid ethyl ester is obtainable by refluxing 2-cyanonaphthalene with ethyl a -bromoisobutyrate in benzene in the presence of zinc.

[Also in Groups XXXV and XXXVI] Multi-layer electric insulating materials, made by wrapping tapes &c. around mandrels or by the hand or mechanical wrapping of electric components and equipment, comprise absorbent sheet material such as paper, or fabrics woven from cotton, glass fibres, or nylon, impregnated with a permanently liquid dielectric and coated with a resin which cures without producing volatile components, viz. an epoxy or unsaturated polyester resin, the resin-being cured after wrapping, for example in the cold or by H.F. or other electric heating. Impregnants comprise transformer oil, or non-inflammable liquids such as chloro-diphenyls alone or mixed with trichlorobenzene or mineral oil, fluorocarbons, or a mixture of mineral oil with hexachlorobutadiene. A hardener may be included in the resin itself or, to prevent its premature hardening, may be wholly or partly included in the impregnant. The wrappings may include mica flakes. Instead of a separate coating the resin and impregnant may be applied together as an emulsion. Alternatively only the outer wrapping layers may be coated and the hardened shell so formed may include conducting material such as wire fabric, graphite or metal foil to form a condenser type bushing. To avoid occlusion of air the wrapping operation may take place during immersion in an insulating liquid, which may be the impregnant or some other liquid. For example the following immersion liquids and impregnants respectively may be used:- kerosene and transformer oil, chlorodiphenyl and mineral oil, dichloro-benzene and chlorodiphenyl. Coating may also be effected beneath the immersion liquid and the resin coating may thereafter be hardened, as by heating the liquid. Impregnation material may also be stored beneath the immersion liquid.

Abstract: 1425465 Making electrical connections RAYCHEM Ltd 27 April 1973 [4 May 1972] 20787/72 Heading B3A A method of making an electrical connection comprises positioning one or more insulated electrical conductors in a hollow electrically conductive outer member, and then squeezing the conductor(s) against the inner surface of the member to displace the insulation and make an electrical contact, the squeezing action being obtained by deforming a mechanically deformable inner member to expand it, or by forcing an inner member into the outer member. In Fig. 2, the ends of two wires 5 having insulation 6 are inserted into a brass ring 4, together with an expansible rivet body 1 which is expanded by drawing the enlarged head 3 of a nail 2 through it, so as to squeeze the wires against the ring, stripping the insulation from them and making electrical contact between the wires and the ring. The ring is preferably slightly resilient, and may be replaced by a hollow cap. The dimensions are preferably such that in the absence of the wires, a small space would remain between the body 1 and ring 4. The connection may be insulated or encapsulated, e.g. by a heat shrinkable sleeve or cap having a meltable inner layer of encapsulating material.
